Abstract
The present invention relates to new compositions for bipolar plates and to methods for manufacturing said compositions. More specifically, the invention relates to a method for manufacturing a composition, comprising the following steps: mixing a thermoplastic polymer in the molten state with a first conductive charge in order to obtain a conductive thermoplastic polymer; grinding said conductive thermoplastic polymer in order to reduce it to a powder; mixing the conductive thermoplastic polymer powder with a second conductive charge.
